Anyway, according to my knowledge, newer model FLX all uses DIP COATING. Meaning the whole rangka kereta soaked into antirust before powder coating. Traditional bitumen spray has been abandoned due to costing/efficiency of anti rust is incompetant.

Advatage of dip:
1) Fast + cover whole vehicle
2) Cost efficient

Disadvantage:
1) Had to further apply sound proof material, whereas bitumen bao all
2) If paint gone, sure anti rust coating also gone, whereas bitumen gone, paint could stay to protect another few months/years

Which is why nowadays Plotong do yearly antirust inspection since this is a whole new chapter of antirust they themselve not familiar with the reliability.

Please sendiri go research GALVANIZE process, as steel factory uses ZINC to coat hotrolled steel for anti rust, protect up to 56 years from rust.

YAB got lotsa work to finish after spent whole day in posopis, if not later tan sri cum & wax 9 me
